Description

Die Erfindung betrifft eine Vorrichtung zum Verfahren von Wellen lagernden und auf Schlitten befestigten Lagerböcken in Schlittenführungen, vorzugweise der Lagerböcke von Formatzylindern und Farbauftragswalzen eines Druckwerks in Schlittenführungen der Farbwerkskonsolen einer Mehrfarbenrotationsdruckmaschine, mit von Elektromotoren, vorzugsweise Schrittmotoren, angetriebenen Spindeltrieben.The invention relates to a device for moving shafts and bearing blocks mounted on slides in slide guides, preferably the bearing blocks of format cylinders and inking rollers of a printing unit in slide guides of the inking unit consoles of a multicolour rotary printing press, with spindle drives driven by electric motors, preferably stepper motors.

Eine derartige Vorrichtung zum Verfahren der Lagerböcke eines Formzylinders und einer Farbauftragswalze einer Flexodruckmaschine ist beispielsweise aus der DE-PS 29 41 521 bekannt. Bei dieser bekannten Vorrichtung sind die die Lagerböcke des Formatzylinders tragenden Schlitten in Schlittenführungen der Farbwerkskonsolen geführt und mit eigenen Spindeltrieben versehen, und die Schlitten der Formatzylinder sind mit weiteren Schlittenführungen für die Lagerböcke der Farbauftragwalzen tragenden Schlitten versehen, die wiederum eigene Spindeltriebe aufweisen. Diese bekannte Vorrichtung arbeitet an sich zufriedenstellend, sie ist aber wegen der zusätzlichen in Schlittenführungen geführten Schlitten,
die ihrerseits wiederum Schlittenführungen für auf diesen verfahrbare Schlitten aufweisen, verhältnismäßig aufwendig.Such a device for moving the bearing blocks of a forme cylinder and an inking roller of a flexographic printing machine is known for example from DE-PS 29 41 521. In this known device, the carriages bearing the bearing blocks of the format cylinder are guided in carriage guides of the inking unit consoles and provided with their own spindle drives, and the carriages of the format cylinders are provided with further carriage guides for the bearing blocks of the inking roller carriages, which in turn have their own spindle drives. This known device works satisfactorily per se, but it is because of the additional slides guided in slide guides,
which in turn have slide guides for slides that can be moved on them, relatively expensive.

Aus der FR-PS 669 672 ist eine Druckmaschine mit mehreren Druckwerken bekannt, bei welcher jeder Formatzylinder und jedes diesem zugeordnete Farbwerk auf einem gemeinsamen Führungsrohr über Führungsbuchsen verschieblich angeordnet und von einer einzigen mit einem Antrieb versehenen Spindel verfahrbar sind. Jedes Farbwerk besteht dabei aus einem jeden Formatzylinder zugeordneten endlosen Einfärbband, das über vier Leitwalzen umläuft. Zum Zwecke des Abrückens des Formatzylinders von dem Druckzylinder und des Wegbewegens des Einfärbebandes von dem Formatzylinder ist die Spindel mit unterschiedlichen Steigungen versehen, wobei der das Farbwerk bewegende Spindelabschnitt eine größere Steigung aufweist als der dem Formatzylinder zugeordnete Spindelabschnitt, so daß bei einer Drehung der Spindel das Farbwerk größere Wege ausführt als die Lager des Formatzylinders. Nachteilig bei dieser bekannten Anordnung ist jedoch, daß sich der Formatzylinder und das Druckwerk nicht unabhängig voneinander bewegen lassen, sondern beide Relativbewegungen bei Antrieb der Spindel ausführen, die zueinander festgelegt sind. Bei der bekannten Vorrichtung ist es somit nicht möglich, den Formatzylinder bei unverändertem Andruck des Farbauftragbandes stärker gegen den Druckzylinder anzustellen. Weiterhin ist es nicht möglich, das Farbauftragsband stärker an den Formatzylinder anzustellen und den Formatzylinder gleichzeitig weniger stark an den Druckzylinder anzudrücken. Wegen der festen Zuordnung der Relativbewegungen der Lagerböcke des Formatzylinders und des Farbwerks ist es bei der bekannten Vorrichtung weiterhin nicht möglich, einen sogenannten Sauberdruck auszuführen, bei welchem nach Druckende das Farbauftragsband von der Farbauftragswalze abgerückt wird, um die Farbauftragwalze und den an die Druckwalze angestellten Formatzylinder noch einige Drehungen weiterlaufen zu lassen, damit die restliche Farbe an das durchlaufende zu bedruckende Material abgegeben wird und somit die Farbauftragswalze und der Formatzylinder von restlicher Farbe befreit werden.From FR-PS 669 672 is a printing press with several printing units known in which each format cylinder and each inking unit assigned to it are arranged displaceably on a common guide tube via guide bushings and can be moved by a single spindle provided with a drive. Each inking unit consists of an endless inking ribbon assigned to each format cylinder, which rotates over four guide rollers. For the purpose of moving the format cylinder away from the impression cylinder and moving the inking ribbon away from the format cylinder, the spindle is provided with different pitches, the spindle section moving the inking unit having a larger pitch than the spindle section assigned to the format cylinder, so that when the spindle rotates, this Inking unit runs larger distances than the bearings of the format cylinder. A disadvantage of this known arrangement, however, is that the format cylinder and the printing unit cannot be moved independently of one another, but instead execute both relative movements when the spindle is driven, which are fixed to one another. In the known device, it is therefore not possible to position the format cylinder more strongly against the printing cylinder while the ink application tape is still being pressed. Furthermore, it is not possible to position the inking tape more strongly on the format cylinder and, at the same time, to press the format cylinder less strongly onto the printing cylinder. Because of the fixed assignment of the relative movements of the bearing blocks of the format cylinder and the inking unit, it is still not possible in the known device to carry out a so-called clean printing, in which after the end of printing the ink application tape is moved away from the inking roller around the inking roller and the format cylinder employed on the printing roller to let it run a few more rotations so that the remaining ink is released to the material to be printed and the inking roller and the format cylinder are freed of any remaining ink.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs angegebenen Art zu schaffen, mit der sich Wellen und insbesondere Formatzylinder und diesen zugeordnete Farbauftragswalzen unabhängig relativ zueinander und zu beispielsweise einem Gegendruckzylinder verstellen lassen.The object of the invention is to provide a device of the type specified at the outset, with which shafts and in particular format cylinders and the inking rollers associated therewith can be adjusted independently of one another and, for example, to an impression cylinder.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß eine Spindel parallel zu einer einzigen Schlittenführung drehbar im Maschinengestell bzw. auf der Farbwerkskonsole gelagert und mit einem Antrieb versehen ist und daß auf die Spindel eine drehfest und axial unverschieblich mit einem Lagerbock bzw. einem Schlitten verbundene Spindelmutter und mindestens eine weitere Spindelmutter aufgesetzt sind, die drehbar, aber axial unverschieblich mit mindestens einem weiteren Lagerbock oder dessen Schlitten verbunden und mit einem eigenen Drehantrieb versehen ist. Die erfindungsgemäße Vorrichtung weist einen verhältnismäßig einfachen Aufbau auf, da zum Verfahren mehrerer Wellen oder Zylinder nur eine einzige Spindel vorgesehen ist. Um mit dieser einzigen Spindel unabhängig voneinander mehrere Stellbewegungen ausführen zu können, ist eine Spindelmutter fest mit einem Schlitten oder Lagerbock verbunden und mindestens eine weitere relativ zu dem verstellenden Lagerbock drehbar, so daß durch Drehung dieser Spindelmutter über einen eigenen Antrieb eine Stellbewegung erreicht werden kann, die unabhängig von der Stellbewegung des ersten Lagerbocks ist. Da jedoch sämtliche Spindelmuttern auf einer Spindel mit gleicher Steigung angeordnet sind, müssen die drehbaren Spindelmuttern über ihre Antriebe Drehungen der Spindel insgesamt durch entsprechende Zusatzdrehungen ausgleichen, wenn trotz der Drehung der Spindel keine Verstellung oder aber eine bestimmte Verstellung gewünscht wird. Drehungen der drehbar in Schlitten gelagerten Spindelmuttern, die überlagerte Drehungen der Spindel kompensieren, lassen sich über steuerbare Motore, beispielsweise Schrittmotore, und Mikroprozessorsteuerungen leicht verwirklichen.According to the invention, this object is achieved in a device of the generic type in that a spindle is rotatably mounted parallel to a single slide guide in the machine frame or on the inking unit console and is provided with a drive, and that on the spindle a non-rotatable and axially immovable with a bearing block or a spindle nut connected to a slide and at least one further spindle nut are attached, which is rotatably but axially immovably connected to at least one further bearing block or its slide and is provided with its own rotary drive. The device according to the invention has a relatively simple structure, since only a single spindle is provided for moving a plurality of shafts or cylinders. In order to be able to carry out several adjusting movements independently of one another with this single spindle, a spindle nut is firmly connected to a slide or bearing block and at least one further is rotatable relative to the adjusting bearing block, so that an adjusting movement can be achieved by rotating this spindle nut via its own drive, which is independent of the actuating movement of the first bearing block. However, since all spindle nuts are arranged on a spindle with the same pitch, the rotatable spindle nuts have to compensate for the rotations of the spindle by means of corresponding additional rotations if, despite the rotation of the spindle, no adjustment or a specific adjustment is desired. Rotations of the spindle nuts rotatably mounted in slides, which compensate for superimposed rotations of the spindle, can be controlled by controllable motors, for example stepper motors, and microprocessor controls easily realized.

Soll die Vorrichtung nur der Ausführung der Stellbewegungen eines Formatzylinders und einer Farbauftragswalze relativ zueinander und zu einem Gegendruckzylinder dienen, brauchen auf der Spindel insgesamt nur zwei Spindelmuttern angeordnet zu sein, die zwei Lagerböcken zugeordnet sind.If the device is only to perform the actuating movements of a format cylinder and an inking roller relative to one another and to an impression cylinder, only a total of two spindle nuts need to be arranged on the spindle, which are assigned to two bearing blocks.

Nach einem weiteren Vorschlag zur Lösung der Aufgabe lassen sich in einfacher Weise unterschiedliche Stellbewegungen dadurch verwirklichen, daß eine Spindel parallel zu einer einzigen Schlittenführung drehfest und axial unverschieblich im Maschinengestell bzw. auf der Farbwerkskonsole gehaltert ist und daß auf die Spindel mindestens zwei Spindelmuttern aufgesetzt sind, die jeweils mit einem Lagerbock bzw. dem diesen tragenden Schlitten drehbar aber axial unverschieblich verbunden und mit jeweils einem eigenen Drehantrieb versehen sind. Da bei dieser Ausführungsform die Spindel starr gehalten ist, brauchen die Antriebe der Spindelmuttern Drehungen der Spindel nicht zu berücksichtigen und nicht zu kompensieren. Auf die Spindel lassen sich wiederum mehr als zwei Spindelmuttern aufsetzen, wobei aber nur zwei Spindelmuttern erforderlich sind, wenn die Stellbewegungen eines Formatzylinders und einer Farbauftragswalze relativ zueinander und relativ zu einem Gegendruckzylinder gesteuert werden sollen.According to a further proposal to solve the problem, different adjusting movements can be realized in a simple manner in that a spindle is held in a rotationally fixed and axially immovable manner parallel to a single slide guide in the machine frame or on the inking unit console and that at least two spindle nuts are placed on the spindle, which are each rotatably but axially immovably connected to a bearing block or the carriage carrying it and each provided with its own rotary drive. Since the spindle is held rigidly in this embodiment, the drives of the spindle nuts do not need to take rotations of the spindle into account and do not have to compensate for them. In turn, more than two spindle nuts can be placed on the spindle, but only two spindle nuts are required if the actuating movements of a format cylinder and an inking roller are to be controlled relative to one another and relative to an impression cylinder.

Zweckmäßigerweise sind die relativ zu den Lagerböcken drehbaren Spindelmuttern in Buchsen gehaltert, die drehbar in den Lagerböcken gelagert sind. Die Buchsen können mit diese verlängernden Hülsen versehen sein, auf die Antriebszahnräder befestigt sind. Diese Antriebszahnräder können über Riementriebe mit den Abtriebszahnrädern der Elektromotore bzw. der Schrittmotore oder der von diesen angetriebenen Reduziergetriebe angetrieben sein. Zweckmäßigerweise sind den Lagerböcken jeder Seite der Wellen oder der Format- und Auftragswalzen eigene Spindeltriebe zugeordnet, so daß bei entsprechender Steuerung der Triebe auch eventuelle Schrägstellungen der Welle und/oder Walzen erreicht oder kompensiert werden können.The spindle nuts, which are rotatable relative to the bearing blocks, are expediently held in bushings which are rotatably mounted in the bearing blocks. The bushings can be provided with these extending sleeves, on which drive gearwheels are attached. These drive gearwheels can be driven via belt drives with the output gearwheels of the electric motors or the stepper motors or the reduction gear driven by them. Expediently, the bearing blocks on each side of the shafts or the format and application rollers are assigned their own spindle drives, so that if the drives are appropriately controlled, any inclined positions of the shaft and / or rollers can also be achieved or compensated for.

Die in Fig.1 dargestellte Flexodruckmaschine 1 weist einen zentralen Gegendruckzylinder 2 auf, dem insgesamt acht Druckwerke 3 zugeordnet sind. Jedes dieser Farbwerke 3 weist eine Farbwerkskonsole 4 auf, mit der zwei Lagerböcke 5 und 6 beispielsweise über Schrauben fest verbunden sind. In den Lagerböcken 5 und 6 ist eine Spindel 7 drehbar gelagert (Fig.2). Zum Zwecke der Drehung dieser Spindel 7 ist auf ihr linkes Ende ein Zahnrad 8 aufgekeilt, das über einen Zahnriemen 9 mit dem Ritzel 10 eines Schrittschaltmotors 11 verbunden ist. Letzterer ist ebenfalls mit dem Lagerbock 5 verbunden. Zwischen den beiden Lagerböcken 5 und 6 ist eine farbwerkskonsolenfeste lineare Führung 12 vorgesehen, auf der zwei Schlitten 13 und 14 aufruhen. Mit den Schlitten 13 und 14 sind Lagergehäuse 15 und 16 fest verbunden, wobei in dem Lagergehäuse 15 eine Rasterwalze 17 und in dem Lagergehäuse 16 der entsprechende Formatzylinder 18 auf nicht dargestellte Weise antreibbar gelagert sind. Beide Gehäuse 15 und 16 weisen jeweils eine abgesetzte Bohrung 19 und 20 auf, die miteinander fluchten. Durch diese beiden Bohrungen 19 und 20 ist die Spindel 7 hindurchgeführt. Wie aus der Figur 2 zu erkennen, sit in dem Teil mit größerem Durchmesser der Bohrung 19 eine Buchse 21 fest eingesetzt, wobei die Buchse 21 eine hohlzylindrige Ausdrehung 22 aufweist, in der ene Spindelmutter 23 gelagert ist, die über eine Paßfeder 24 unverdrehbar in der Buchse 21 gehalten ist. Bei Betätigung des Motors 11 wird demnach das Lagergehäuse 15 je nach Drehrichtung des Motors 11 hin- und herbewegt, wobei die Gewindemutter 23 feststeht.The flexographic printing press 1 shown in FIG. 1 has a central impression cylinder 2, to which a total of eight printing units 3 are assigned. Each of these inking units 3 has an inking unit console 4, with which two bearing blocks 5 and 6 are firmly connected, for example by means of screws. A spindle 7 is rotatably supported in the bearing blocks 5 and 6 (FIG. 2). For the purpose of rotating this spindle 7, a gear wheel 8 is wedged onto its left end, which is connected via a toothed belt 9 to the pinion 10 of a stepping motor 11. The latter is also connected to the bearing block 5. Between the two Bearing blocks 5 and 6, a linear guide 12 fixed to the inking unit console is provided, on which two slides 13 and 14 rest. Bearing housings 15 and 16 are firmly connected to the slides 13 and 14, an anilox roller 17 being mounted in the bearing housing 15 and the corresponding format cylinder 18 being drivably mounted in the bearing housing 16 in a manner not shown. Both housings 15 and 16 each have a stepped bore 19 and 20 which are aligned with one another. The spindle 7 is passed through these two bores 19 and 20. As can be seen from FIG. 2, a bushing 21 is firmly inserted in the part with a larger diameter of the bore 19, the bushing 21 having a hollow cylindrical recess 22 in which a spindle nut 23 is mounted, which is immovable via a feather key 24 in the Socket 21 is held. When the motor 11 is actuated, the bearing housing 15 is accordingly moved back and forth depending on the direction of rotation of the motor 11, the threaded nut 23 being fixed.

Im Falle des rechten Lagergehäuses 15 ist in den Teil mit größerem Durchmesser der Bohrung 20 ebenfalls eine Buchse 25 eingesetzt, die allerdings gegenüber dem Lagergehäuse 16 drehbar ist. Die Buchse 25 weist wiederum eine innere Ausdrehung 26 auf, in der eine Gewindemutter 27 gelagert ist. Diese Gewindemutter ist über eine Paßfeder 28 drehfest mit der Buchse 25 verbunden. Mit der Buchse 25 ist drehfest ein Zahnrad 29 verbunden, das über einen Zahnriemen 30 mit dem Ritzel 31 eines Motors 32 in Antriebsverbindung steht. Dieser Motor 32 ist mit dem Getriebegehäuse 33 verschraubt, das selbst fest mit dem Lagergehäuse 16 verbunden ist. Beim Betätigen des Schrittschaltmotors 32 wird demnach die Gewindemutter 27 in Drehung versetzt, wodurch die gesamte Einheit (16 und 33) zusammen mit der Gewindemutter 27 auf der Spindel 7 hin- und herbewegt werden kann.In the case of the right-hand bearing housing 15, a bushing 25 is also inserted into the part with the larger diameter of the bore 20, but this bushing can be rotated relative to the bearing housing 16. The bush 25 in turn has an inner recess 26 in which a threaded nut 27 is mounted. This threaded nut is connected in a rotationally fixed manner to the bushing 25 via a parallel key 28. A gear 29 is connected in a rotationally fixed manner to the bushing 25 and is in drive connection with the pinion 31 of a motor 32 via a toothed belt 30. This motor 32 is screwed to the gear housing 33, which is itself firmly connected to the bearing housing 16. When the stepping motor 32 is actuated, the threaded nut 27 is accordingly set in rotation, as a result of which the entire unit (16 and 33) can be moved back and forth together with the threaded nut 27 on the spindle 7.

Soll nun bei einem angenommenen Druckende die Rasterwalze 17 weggefahren werden, wird zunächst einmal der Motor 11 eingeschaltet, worduch sich die Spindel 7 dreht. Da die Mutter drehfest in der Buchse 21 gelagert ist und diese fest mit dem Lagergehäuse 15 verbunden ist, bewegt sich dieses von dem Formatzylinder 18 weg. Der Formatzylinder 18 muß zum Reindruckennoch in der in Figur 2 dargestellten Stellung verbleiben, wobei es zu diesem Zweck erforderlich ist, daß der Motor 32 ebenfalls eingeschaltet wird, derart, daß die Buchse 25 eine Gegendrehung ausführt, so daß das Lagergehäuse 16 am Gegendruckzylinder 2 gehalten bleibt. Nachdem der Formatzylinder 18 sich am Gegendruckzylinder 2 bzw. an der zwischen ihn geführten Bahns sauber gedruckt hat, kann der Motor 32 ausgeschaltet werden, so daß bei weiterer Betätigung des Motors 11 neben dem Lagergehäuse 15 auch das Lagergehäuse 16 mit dem Formatzylinder vom zentralen Gegendruckzylinder abgefahren wird. Je nach Zusammenspiel der Motoren 11 und 32 kann somit jede beliebige Stellung der einzelnen Walzen untereinander erreicht werden. Die Buchse 25 ist durch den Lagerdeckel 34 im Lagerbock 16 gehalten.If the anilox roller 17 is now to be moved away when the printing end is assumed, the motor 11 is first of all switched on, what the spindle 7 rotates. Since the nut is rotatably mounted in the bushing 21 and this is firmly connected to the bearing housing 15, this moves away from the format cylinder 18. The format cylinder 18 must still remain in the position shown in FIG. 2 for printing, for which purpose it is necessary that the motor 32 is also switched on, in such a way that the bushing 25 performs a counter-rotation, so that the bearing housing 16 is held on the impression cylinder 2 remains. After the format cylinder 18 has printed neatly on the impression cylinder 2 or on the web guided between it, the motor 32 can be switched off, so that when the motor 11 is actuated further, the bearing housing 16 with the format cylinder also moves away from the central impression cylinder in addition to the bearing housing 15 becomes. Depending on the interaction of the motors 11 and 32, any position of the individual rollers with one another can thus be achieved. The bushing 25 is held in the bearing block 16 by the bearing cover 34.

Bei dem Ausführungsbeispiel nach Fig.2 können nur durch Betätigung des Motors 11 beide Lagergehäuse 15,16 gemeinsam verstellt werden, ohne daß diese eine Relativbewegung zueinander ausführen, wobei es dann jedoch zweckmäßig ist, den Motor 32 gebremst zu halten.In the embodiment according to FIG. 2, the two bearing housings 15, 16 can only be adjusted together by actuating the motor 11, without these making a relative movement to one another, but it is then expedient to keep the motor 32 braked.

Die Fig.4 zeigt ein Ausführungsbeispiel das sich von dem nach Fig.2 zunächst einmal dadurch unterscheidet, daß die Spindel 7' in den Lagerböcken 5' und 6' drehfest gehalten ist. Wie im Ausführungsbeispiel nach Fig.2 ist die Gesamtanordnung hinsichtlich des Lagergehäuses 16' identisch mit dem Lagergehäuse 16. Das Lagergehäuse 15' enstpricht nun nicht dem Lagergehäuse 15 gemäß Fig.2, sondern ist spiegelbildich identisch ausgebildet, wei das Lagergehäuse 16'. Soll nun zum Druckende zunächst einmal die Rasterwalze 17' von dem Formatzylinder 18' weggefahren werden, wird der Motor 32'' eingeschaltet, wodurch über das Zahnrad 29'' die Hülse 25'' und mit dieser Hülse auch die Gewindemutter 27'' in Drehbewegung versetzt. Hierdurch bewegt sich die gesamte aus Lagergehäuse 15' und Getriebegehäuse 33' gebildete Einheit von dem Formatzylinder 18' weg. Unabhängig davon, ob nun der Motor 32'' weiterbetrieben wird oder nicht, kann nach einer gewissen Zeit der Motor 32' eingeschaltet werden, wodurch dann auch über das Zahnriemenrad 29' die Buchse 25' und die Gewindemutter 27', das Lagergehäuse 16' und damit auch der Formatzylinder 18' von dem zentralen Gegendruckzylinder 2 wegbewegt wird. Bei dem Ausführungsbeispiel nach dieser Figur 4 ist es also ebenfalls möglich, durch entsprechendes Einschalten der Motoren 32' und 32'' die Lagergehäuse 17' und 16' unabhängig voneinander zu bewegen.4 shows an embodiment which differs from that according to FIG. 2 first of all in that the spindle 7 'is held in the bearing blocks 5' and 6 'in a rotationally fixed manner. As in the exemplary embodiment according to FIG. 2, the overall arrangement with regard to the bearing housing 16 'is identical to the bearing housing 16. The bearing housing 15' now does not correspond to the bearing housing 15 according to FIG. 2, but is of mirror-inverted design, white the bearing housing 16 '. If, at the end of printing, the screen roller 17 'is to be moved away from the format cylinder 18', the motor 32 '' switched on, which causes the sleeve 25 '' via the gear wheel 29 '' and, with this sleeve, the threaded nut 27 '' to rotate. As a result, the entire unit formed from the bearing housing 15 'and the gear housing 33' moves away from the format cylinder 18 '. Regardless of whether the motor 32 '' continues to be operated or not, the motor 32 'can be switched on after a certain time, as a result of which the bushing 25' and the threaded nut 27 ', the bearing housing 16' and so that the format cylinder 18 'is also moved away from the central impression cylinder 2. In the exemplary embodiment according to this FIG. 4, it is therefore also possible to move the bearing housings 17 ′ and 16 ′ independently of one another by appropriately switching on the motors 32 ′ and 32 ″.

Bei Betrachtung der Figur 3 wird deutlich, daß ebenso die Möglichkeit besteht, Formatzylinder und Rasterwalze gegeneinander zu versetzen, das heißt sie aus ihrer Achsparallelität herauszubringen. Desweiteren ist es möglich, Zylinder und Rasterwalze gegeneinander zu versetzen, das heißt sie aus ihrer Achsparallelität herauszubringen. Desweiteren ist es möglich, Zylinder und Rasterwalze achsparallel zu belassen und beide gemeinsam gegenüber dem zentralen Gegendruckzylinder 2 schräg anzustellen. Diese Schrägstellungen dienen im wesentlichen zum Toleranzausgleich bei nicht ganz zylindrischen Druckwalzen und Dickenunterschieden im Klischee.When viewing FIG. 3, it becomes clear that there is also the possibility of displacing the format cylinder and anilox roller against one another, that is to say bringing them out of their parallel axes. Furthermore, it is possible to offset the cylinder and anilox roller from each other, that is, to bring them out of their parallel axes. Furthermore, it is possible to leave the cylinder and anilox roller parallel to the axis and to position both at an angle relative to the central impression cylinder 2. These inclinations essentially serve to compensate for tolerances in the case of printing cylinders that are not entirely cylindrical and differences in thickness in the printing block.
